To LN whom it may conce/771,.'

Be it known that we, ROBERT MEYER and JosErH PERRIN, engineers, citizens ofthe French Republic, residing' at Cours, in the Department du Rhne, France, have invented new and useful Improvements in and Relating' to Combing-Oylinders for Oombing'1\fachines, of which the following' is a specification.

This invention relates to a combing-cylinder which is applicable to combing-machines in general, and more particularly to machines of the .Heilmann class for the combing' of wool, silk, cotton, and other fibers.

It is known that with the needle-segment of combing-cylinders of large diameter already in use it has been necessary to employ complicated apparatus or devices to permit only the penetration of a portion of' the fiber into the needles. On the other hand, in the Heilmann type of combing-machine having a segment of reduced radius the segment, by reason of' its short periphery, will not be able to carry enough rows of needles to insure the proper combing' of the fiber.

The combing-cylinder which is the subject of the present improvements combines the advantages of a cylinder of' large diameter with the advantages of a cylinder of' small diameter.

The improved combing-cylinder is illustrated in the accompanying drawings, of' which-- Figure 1 shows the cylinder in vertical cross-section working in conjunction with a nipper of a machine of the Heilmann type. Fig. 2 illustrates it in longitudinal section. Modifications are represented in Figs. 3 and ef, in which Fig. 3 is a longitudinal sectional view of part of such a modified cylinder, and Fig. 4 represents the modified parts in end elevation working in conjunction with a nipper of any desired type.

1 is a cylinder or drum upon or within which are circularly disposed and arranged a convenient number of smaller combing-cylinders 2 3 5 6 7, which when the machine is in operation are preceded by a small segment of the drinn 1, upon which reduced or small segment 8 are arranged rows of' needles obliquely to lines on the drum parallel with the drum-axis. The pitch or setting of the needles upon the small needle-cylinders becomes progressively finer from 2 to '7, following the usual practice in combing'- machines. The smaller cylinders are mounted upon shafts 9.

The main cylinder 1 is keyed to a shaft 10, which is capable of giving to the complete cylinder and its parts a rotary motion in the direction of the arrow On the shafts 9 are secured pinions gearing with a central wheel 12 in such a manner that the rotation of the cylinder 1 in the direction of the arrow :1' causes the shafts 9 to rotate in the direction of the arrows y, the attached small cylinders 2 3 i (i T consequently rotating in the same direction of the arrow The nippel' 13 14 of the combing-machine is represented in its open position in dotted lines and in its closed position in full lines in Fig. 1 of the drawings. fhen it is in its closed position, the liber of' the lap7 15 is submitted to the combing action of-the coarse needles of the small or reduced segment 8 first, then successively to the graduated action of the small cylinders 2 3 Lf 6 7 as the shaft 10 is rotated.

In addition to the common movement in the direction of the arrow a' around the center of the drum 1 the smaller cylinders have also a planetary movement imparted to them of' rotation around their own axes in the direction of the arrows y, consequent upon the engagement of the pinions 11 with the wheel 12, which may be either fixed or moving.

lVhen the lap is comparatively clearer free from short fibers or other impurities, a fixed wheel 12 may be used, as the length of the segment of each of the small cylinders which will then engage with thelap will be sufficient. lVhen, however, the lap requires considerable treatment, the wheel 12 instead of being fixed to the frame of the machine may also rotate. To effect this, it may be secured to a wheel 16, which may be driven by a pinion 1T. Then desired, the wheel 12 maybe driven in the direction of the arrow z, and thus cause an increased speed of rotation of the small cylinders around the axes in the direction of the arrows r/ and increase the combing' action. The wheel 12 may have its rotation continued or varied or discontinued by well-known mechanical means. lVith this arrangement a great range of combing' action may be obtained.

lV ith the devices illustrated in Figs. 1 and 2 the small cylinders have a continuous planetary motion imparted to them when the machine is in use, caused by the constant engagement of their pinions with the central l fixed toothed wheel 12; but as the work ef'- fected bythe small cylinders 2 3 41 5 6 7 may IOO be done bya length of arc or segment of such cylinders which is about equal to the length of the ber under treatment the small cylinders may be so mounted as to rotate intermittently and only within the fiber. How the desired intermittent motion may be obtained is represented in Figs. 3 and 4 of the drawings. 1n this modification the toothed pinions formerly shown on the shafts of the small cylinders are replaced by four toothed wheels or star-wheels 25, which in conjunction with disks 26, having curved recesses formed on their peripheries, are secured to the shafts 13, which carry the small cylinders now indicated by the figures 19 20 21 22 23 24. 27 is a fixed disk, around the periphery of which o ne or other ofthe recessed faces of all the disks 26 slide and engage. An enlargement or recess in the disk 27 permits ot' the partial rotation of the disks 26 when desired. As the cylinder 1 rotates the whole of the small cylinders are carried round with it without rotating until they successively arrive at the section-finger 28, which is secured to a bracket 29, formed upon or attached to the sleeve or socket 30. Each star-wheel as it comes against the action-nger is successively turned thereby through a quarter of a revolution, carrying' with it its attached small cylinder, either 19, 20, 21, 22, 23, or 24. Then the combing is accomplished by either of the two systems described, and the nippers 13 and 14 move in the known manner and open, as indicated by the broken lines, to permit the passage of the sliver, which is seized by the fiuted gripping or drawing rollers 31 and 32. The tail of the fiber not combed traverses the upper rectilinear comb 33.

The lubrication ot` the bearings of the small com hing-cylinders is effected by the contact of their bearing-surfaces withwicks 34, soaked with lubricant and lodged in wells formed in the cylinder 1.
